Does the job, but breaks
5 November 2021

Round up definitely does the job, but the trigger on the sprayer broke half way through using the bottle.Recommend roundup, but not this applicator.

Good

Kills small weeds straight away, though need to be used a few times for tougher larger weeds

Great stuff......Quick to use
4 July 2020

It was great to use. Not having to mix any harsh chemicals.....already done. Convienent bottle and sprayer to use. Can get straight into the job with no mucking around.

How is this allowed to be sold?
22 October 2021

The active ingredient in Roundup causes cancer according to the WHO. Why are people still buying this weedkiller with that risk?

Not great,
10 September 2020

I thought this sprayer would be easy to use, but I ended up cutting it open and pouring it into my usual sprayer.
